Our heavy-duty Large Sheet Pan combines the strength and durability of steel with the superior heat conduction of aluminum—just like the pans professional bakers choose. The improved coating prevents food from sticking and keeps your pan looking great. The rolled edges and wire rims prevent warping, and the high sides keep food from overflowing. The large size is great for extra-large batches of cookies. Details 15½” x 10” x 1”. Heavy-gauge aluminized steel resists corrosion and provides even heat distribution.
